LATRINE.

Specification of Letters Patent.

Patented Mar. 5, 1912.

To all whom it may concern.-

Be it known that I, EUGENE B. BARTLETT, a citizen of .the United States,and a resident of Oleveland, in'the county of Guyahoga and State ofOhio, have invented a new and Improved Latrine, of which the followingis a full, clear, and exact description.

This invention relates to certain improvements in latrines adapted foruse in public buildings, such as schools, hospitals, depots, and thelike, and more particularly involves certain improvements over theconstruction disclosed in United States Patent No. 57 3,7 44, December22, 1896.

The object of the invention is to maintain a more uniform and continuoussupply of water to the inclined sides of the body portion, and topositively prevent the passage of paper or the like into the ventilatingduct.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures, and in which- Figure 1 is alongitudinal section through one end of a latrine constructed inaccordance with my invention; Fig. 2 is a transverse section on the line22 of Fig. 1; Fig. 3 is a front elevation of the parts shown in Fig. 1;and Fig. 4 is a perspective view of the means employed for supplyingwater to the walls of the body.

The body of the latrine is made up of a plurality of sections bolted orotherwise rigidly secured together, each section having front and rearinclined walls 10 and 11 and a curved bottom 12, the walls and bottombeing preferably formed integral. At one end of the terminal section isprovided a water inlet connection 13 for facilitating flushing, thebottom and sides being of such form as to facilitate the flow of thewater longitudinally of the latrine, as in the construction disclosed inthe patent above referred to. Each section is provided with two airinlet openings 14: at the front edgethereof at opposite sides of thecenter, and is provided with an air outlet 15 at the upper edge of therear side thereof at the center. The air outlet is connected to aventilating duct having any suitable means for creating a circulation ofair therethrough, and this duct involves an elbow 16 preferably formedof enameled metal and leading from the outlet upward. In the connectionbetween the elbow and the outlet there is inserted a perforated mctalplate 17 serving to positively prevent the passage of any foreignmatterinto the ventilating duct, but, at the same time, not interfering withthe free passage of air. The edges of the plate are preferably clampedbetween the base flanges of the elbow and oppositely-clamped flanges,around the air outlet, as illustrated in Fig. 2.

To deliver a continuous and uniform sheet or curtain of water to theinclined side walls of the body, there has been previously employed apipe having a series of small perfo rations therein. In thisconstruction, the

openings are liable to become clogged and the portion of the pipefarthest from the source of supply does not always receive the samequantity of'water the portion of the pipe adjacent the supply does. Toobviate these objections, I provide a series of troughs 18, eachsubstantially V-shaped in cross section and each of a lengthsubstantially equal to the length of one section or unit of the latrine.One edge of each trough is provided with a series of notches orcorrugations, while the opposite edge is provided with lugs 19 adaptedfor the insertion of screws or bolts for holding the trough to the wallsof the body. Two of these troughs are employed for each section, onetrough being secured to the, front wall 10 adjacent the upper edgethereof and the other being attached to the rear wall 11 adjacent itsupper edge. The notched edge of each trough is slightly lower than theopposite edge thereof, so that the water flows through between thenotches and down the side of the trough into engagement with the sidewall of the body. By means of the screws or bolts entering the lugs 19,the elevation of the ends of the troughs may be adjusted so as tomaintain a uniform overflow of the trough throughout the length thereof.

Two separate water supply pipes 20 are provided, one for each series oftroughs along the walls. Each pipe is provided with one or moredepending branch pipes 21 leading into each trough to deliver waterthereto. The branch pipes are of such size that there is no liability oftheir becoming clogged or choked'to interfere with the free delivery ofwater, and the very nature of the troughs is such that the free overflowof water cannot be readily interfered with.

The water is supplied through the pipes under sufficient pressure sothat each of the troughs along the length of the latrine receivessubstantially the same amount of wa ter, and a continuous and uniformcurtain or sheet of water is presented upon each of the side walls ofthe body.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent:

1. A latrine, including a body having inclined sides and means forwetting said sides including an overflow trough adjacent the upper edgeof each of said sides and supply pipes for delivering water to eachtrough, each of said troughs being substantially V-shaped in crosssection and having a notched or serrated overflow edge and a lowerunbroken dripping edge, and independent means adjacent opposite ends ofeach trough for securing the same to the side of the body and permittingof a vertical adjustment to maintain a uniform overflow of the troughsthroughout the length thereof.

2. A latrine including a body having an inclined side and means forwetting "said side, including an overflow trough adjacent to the upperedge of the side, and a supply pipe for delivering water to the trough,the

trough being substantially V-shaped in cross section and having anunbroken dripping edge at the bottom thereof, one side of said troughbeing located substantially against 4 section and having an unbrokendripping edge at the bottom thereof, one side of the said trough beinglocated substantially against the side of the body and its other sideinclined to the first mentioned Si e at such an angle that the wateroverflowing the second mentioned side flows directly along the outersurface of the side and onto the side of the body to flush the latter.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

EUGENE BISHOP BARTLETT.
